Hey Peter, I just wanted to let you know I followed your advice and did the tests and seem to have come up with a workable porcelain slip. Much appreciated! P.S. Thanks for that jeff. I do sometimes go to 1.7 if I can't get it right but nice to know some people go even lower!

Thank you for the links Peter. I'll have a look and get back to you. We found previously that the antiprex helped with the slip solution if we had added too much alcosperse. Tom, the measurements are mL. Apologies for not stating what alcosperse and antiprex are and their units.

Hi all, I was wondering if anyone has used Imery's replacement for SSP, Kaopearl, in a successful slip? I've tried a variety of recipes, the last being this one which I used to use for SSP. There would always be slight adjustments but now the slip seems to be unable to take more deflocculant and I'm concerned about raising the water too high to keep the specific gravity in the correct range of about 1.75 -1.78 28l water 250 antiprex 450 alcosperse 35kg China clay (SSP) 25kg feldspar 11kg silica Any thoughts would be appreciated.
